Yeah sure, there has been wrestlers that are a lot more horrible talent wise then him, Del Rio at least knows what the fuck he's doing in the ring. BUT GOD DAMN HE'S SO FUCKING BORING. He wrestles the same slow, drawn out match every week, cuts the same cliche "bad guy" promo every week, his feuds with Sheamus and Orton are just a bunch of nothing that go on for a seemingly infinite amount of time, his gimmick is extremely thin and he looks like a generic, bland, latin CAW. Completely unremarkable in ever sense of the word.

I actually think he could be entertaining, just not as a "serious" heel main eventer. It's time they start using Ricardo as a wrestler, put him in a tag team with ADR, they could even turn face. Just for the sole fact that Del Rio is a great wrestler he's not the most boring ever (Khali anyone?), but he's close.

From a wrestling stand point I love his matches.. The guy is a great in ring talent and anyone that says otherwise is a delusional twit. His gimmick is in a paradox between good, and sucking.. It's not good, but also it doesn't suck.. It just hovers in that "not a single fuck was given that day" gray area.. The dude has always had the potential to be an awesome heel and the gimmick has got a tad better over the year but WWE still settled for the status quo Mexican heel package and well.. It doesn't work anymore.
